Final answer:
The nurse should advise the parents of a child taking cyclosporine post-renal transplant to monitor for signs of infection due to the immunosuppressive action of the drug.
Step-by-step explanation:
The nurse preparing a teaching plan for parents of a 6-year-old child who is taking cyclosporine following a renal transplant would include instructions about monitoring the child for signs of infection. Cyclosporine works by suppressing the immune system to prevent organ rejection, which inherently increases the risk of infections due to the decreased immune response. It is critical for parents to monitor for indications of infection, as children taking immunosuppressants like cyclosporine are more susceptible to infections that their bodies may not be able to fight as effectively.
